When Sebastian left his house in the morning, his cell phone battery was partially charged. The charge remaining in Sebastian's

battery, as a percentage, can be modeled by the equation B=-9t+81, where t is the number of hours since Sebastian left his house. What is the slope of the equation and what is its interpretation in the context of the problem?

Answer:

The slope is -9

and the interpretation is that the percentage that drops on the battery per hour is 9%

Step-by-step explanation:

Generally, the equation of a straight line can be represented by the formula;

y = mx + b

where m is the slope and b is the y-intercept

With respect to the given equation, the slope is -9

What it means is that the percentage that drops per hour on the battery is 9%

Greg is in a car at the top of a roller-coaster ride. The distance, d, of the car from the ground as the car descends is determi
ANTONII [103]

Answer:

It takes 3 seconds over the interval [0,3]

Step-by-step explanation:

To find when the roller coaster reaches the ground, find when d=0.

0=144-16t^2

To solve divide each term by 16 and factor:

\frac{0}{16}=\frac{144}{16} -\frac{-16t^2}{16}  \\0= 9 - t^2\\0=(3-t)(3+t)

Solve for t by setting each factor to 0.

t-3=0 so t=3

t+3=0 so t=-3

This means the car is in the air from 0 to 3 second.
